3 Claims.

This invention relates to new and useful improvements on a special tool or device byvmeans of which glass blowers when producing glass goblets, flower vases or other glass articles having standard flange feet may be crimped and artistically formed.

The main object of my invention is the construction of a specially designed forming device by means of which the foot of a glass goblet and similar articles may be crimped formed, as shown, illustrated and described.

I attain these objects by the mechanism illustrated in the accompanying drawing in which- Fig. 1 represents a plan view of my goblet foot forming device.

Fig. 2 represents a portion of the form showing one of the raised crimping forms.

' Fig. 3 represents a pivoted foot forming attachment which is pivotally attached ,to each side of the main foot forming device.

Fig. 4 represents a side elevation of my foot forming device showing the pivotally mounted portion in a raised position.

Fig. 5 represents a side view of the oblet foot forming device, showing a goblet foot in the proper position to be pressed in the new form.

Referring to the figures by characters of reference I designates the base or die of the device. This base has its upper surface of any desired configuration for the purpose of forming radial corrugations in the foot or base of the goblet to be made. In the present instance there is provided an annular series of radial V-shaped ribs 2 forming corresponding grooves between them, both the ribs and grooves increasing in size toward ,the periphery of the die and terminating at the margin of a central or hub portion shown at 2a. i

Hingedly connected to diametrically opposed portions of the periphery of base I are levers I0 having long arms and short arms as shown. The short arms are secured to opposed arcuate pressure members having pressure fingers converging from the inner or concave surfaces of ,the mem- 45 bers and equal in number to the number of grooves formed between the ribs 2. These fingers are also spaced apart distances equal to thedistances between the centers of the grooves so that all of the fingers will overlie the centers of the grooves and extend toward each otherat the same angle as do the center lines of the grooves.

Springs 5 connect the short arms of levers III to the peripheral portion of base I as shown particularly in Figure 4.

The long arms of the levers I 0 are connected by links 9 to the cross head I I which, in turn, is slidably mounted on a stem 8 projecting from and fixedly attached to the center of the base I. When it is desired to use the device, the blank to be shaped is supported by one hand while the 5 other hand of the operator engages a handle I on base I and supports said base, the cross head I'I being held up by one or more fingers on the hand so as to keep the springs 5 under tension. If preferred, the base i can be supported en the knees 10 of the operator with ,the two levers I0 between the knees. After the circular fiat foot of the blank has been formed in the usual way and while said foot is still hot, it is applied to ,the base as shown at X in Figure 5 so that the fingers 4 will 15 be out of engagement therewith. The stem of the glassware projecting from the foot is cool and hard so that it can be used as a means for pressing the foot firmly against the base I. The cross head I I, which has been pulled up to the position shown in Figure 4 can then be released and springs 5 will actuate the levers II). Obviously this relative movement will cause the fingers 4 to press downwardly on those portions of the foot X bridging the grooves in the base with the result that ,the hot glass will be pressed down into these grooves and the foot will be given a shape predetermined by the arrangement and contours of the ribs on the base and of the fingers acting on the foot. Any suitable means may be employed for connecting the links 9 to the levers III. For example short links I2 can be used for this purpose. Links Q are pivotally joined to the cross head I I as shown at I3. For the purpose of joining the levers It) to the base I brackets I 4 can be provided, these brackets being joined to the bottom of the base I in any suitable manner and having portions which straddle and are pivotally connected to the levers as shown at 55.

Importance is attached to the fact that the fingers t are spaced apart. Thus that portion of the glass between the fingers is not restrained in any Way but is free to fiow in any direction necessary in order to facilitate the adaptation of the foot of the goblet or the like to the contour of the base or die I. Thus the glass foot will not become distorted as in cases where the glass is confined during ,the pressing operation. Consequently an attractive foot having crimps free from blemishes can be produced.

It has been found that by using a device such as herein described, the formation of the article of glassware can be carried on With one heating. It does not become necessary to reheat it before shaping the foot. This is due to the fact 55 that the shaping operation can be carried on quickly and constiutes bending operations only and not operations in which the entire surfaces of the foot are engaged and subjected to pressure.

What is claimed is:

, 1. A device for shaping the foot of a glass goblet or the like while hot, including a base having radial ribs separated by radial grooves, a stem extending from the base, a member slidable on the stem, opposed levers pivotally connected to the base, fingers on said levers movable into position within the grooves in the base, connections between the levers and the slidable member, and resilient means for automatically shifting said slidable member in one direction along the stem and moving ,the fingers and levers relative to the base.

2. A device for forming the foot of a glass goblet or the like while hot, including a base having radial grooves and radial ribs, a stem extending from the base, a member slidable on the stem, levers connected to and mounted to swing relative to .the base, connections between said levers and slidable member for transmitting motion from one to the other, fingers extending from the levers and overlying the base for movement into engagement with ,the foot of the goblet or the like While the goblet rests on the base, thereby to bend the foot over the ribs and into the grooves, and resilient means for holding the fing r and the slidable member normally in predetermined positions relative to the base.

3. A device for forming the foot of a glass goblet or the like while hot, including a base having radial grooves and ribs, a stem extending from one face thereof, a member slidable on the stem, levers pivotally connected to and extending across the margin of the base, motion transmitting connections'between the slidable member and the levers, an arcuate pressure member carried by each lever, a plurality of converging pressure fingers extending from each of said members and adapted to force portions of the hot glass foot into the grooves and over the ribs, and resilient means for holding the pressure fingers and the slidable member normally in predetermined positions.
